Renesas ISLA216P20IRZ

Overview

ISLA216P20IRZ from Renesas Electronics is a 16-bit, 200MSPS analog-to-digital converter using FemtoCharge™ technology on standard CMOS. It delivers 76.6dBFS SNR at 30MHz input and 72.6dBFS at 363MHz, with 87dBc SFDR at low frequency and 80dBc at RF, operating from a single 1.8V supply across –40°C to +85°C. It serves as the front-end digitizer in high-speed radar and SDR signal chains.

For engineers reviewing the ISLA216P20IRZ datasheet, ISLA216P20IRZ pinout, ISLA216P20IRZ application, or ISLA216P20IRZ equivalent, key selection criteria include its LVDS/CMOS dual-output flexibility, 75fs aperture jitter, 700MHz full-power bandwidth, SPI-configurable gain/offset, and support for multi-ADC synchronization in time-coherent systems.

Technical Context

The ISLA216P20IRZ implements a pipeline ADC architecture with digital error correction and integrated clock duty cycle stabilizer. Its 75fs RMS aperture jitter enables high-fidelity sampling of IF signals up to 363MHz while maintaining 72.6dBFS SNR.

It supports both DDR LVDS and LVCMOS digital outputs, configurable via RLVDS pin and internal register settings. The SPI interface provides fine-grained control over gain, offset, clock divider, nap/sleep modes, and built-in test patterns - all synchronized to the 200MSPS sample clock.

Key Specifications

Pinout & Package

ISLA216P20IRZ is housed in a 72-lead QFN package (10mm × 10mm, 0.5mm pitch) with exposed thermal paddle connected to AVSS. Pin functions differ between LVDS and CMOS output modes; LVDS mode uses differential data pairs (e.g., D0P/D0N), while CMOS mode uses single-ended D0–D14.

FAQ

What is the maximum analog input frequency supported by the ISLA216P20IRZ?

The ISLA216P20IRZ has a full-power bandwidth of 700MHz, meaning it maintains specified SNR and SFDR performance for sinusoidal inputs up to 700MHz. At 363MHz input, it delivers 72.6dBFS SNR and 80dBc SFDR - confirming usable RF sampling capability well into UHF band. Performance degrades gradually beyond this point due to analog front-end roll-off.

Does the ISLA216P20IRZ support both LVDS and CMOS digital outputs?

Yes, the ISLA216P20IRZ supports selectable DDR LVDS or LVCMOS outputs. Output mode is configured via the RLVDS pin and internal SPI registers: tie RLVDS to OVSS for LVDS operation; leave floating or pull high for CMOS. Pin assignments differ - LVDS uses differential pairs (D0P/D0N), while CMOS uses single-ended D0–D14.

How does the SPI interface of the ISLA216P20IRZ interact with ongoing ADC conversion?

The SPI interface of the ISLA216P20IRZ operates asynchronously to the ADC sample clock, allowing configuration and readback without halting conversion. Commands such as gain/offset trim, nap/sleep entry, or test pattern activation take effect on the next sample boundary. Latency remains fixed at 10 cycles regardless of SPI activity.

What is the power-up and calibration behavior of the ISLA216P20IRZ?

The ISLA216P20IRZ performs automatic power-on calibration including offset, gain, and linearity correction. Full calibration completes within 10ms after RESETN release. Optional user-initiated recalibration can be triggered via SPI and takes <1ms. Temperature drift is compensated using on-chip IPTAT current and stored calibration coefficients.

Can multiple ISLA216P20IRZ devices be synchronized for coherent sampling?

Yes, the ISLA216P20IRZ supports deterministic multi-ADC synchronization via shared CLKP/CLKN, CLKDIVRSTP/N, and SPI-controlled latency alignment. The clock divider and synchronous reset ensure phase-aligned sampling across devices, enabling time-interleaved or beamformed architectures with sub-sample timing precision.
